Unless you need something more complex and are
only worried about the top page, take the path of least resistance: just include a flag in the variables you pass to your view, then check for the flag.
Code:
// In the controller
$this->load->vars(array(
'top_page' => TRUE
));
$this->load->view('top_page');
// In the view
<?php if (isset($top_page) && $top_page === TRUE):?>
<!-- Top page only content here -->
<?php endif;?>
